SUMMARY

This Annual Report details the monitoring activities during the 2007 growing season on the Cox Mitigation Site. Construction of the site was completed in December 2005. The 2007 data represent the results from the second year of hydrologic, vegetation, and stream morphology monitoring. Restoration of the Cox site involved stream restoration, stream enhancement, riverine wetland restoration, and non-riverine wetland restoration. Construction included a stable meandering channel across prior-converted hydric agricultural fields. The channel was designed and constructed with natural channel design techniques. Wetland restoration activities included raising the water table by filling drainage ditches and creation of microtopography across the site. After construction it was determined there was 7,292 linear feet of stream restoration, 350 linear feet of stream enhancement, 26.8 acres of riverine wetland restoration, and 16.9 acres of nonriverine wetland restoration. Appendix A contains the As-Built survey. This Annual Report presents data from the 12 hydrology monitoring gauges, 22 vegetation monitoring plots, crest gauge, rain gauge, and 16 cross sections, as required by the approved Restoration Plan. In 2007 six of twelve hydrology monitoring gauges recorded hydroperiods of at least 7 percent of the growing season despite abnormal drought conditions. The gauges that did not record a success criteria hydroperiod did record hydroperiods ranging from 1 percent to 5 percent of the growing season, and these gauges did correlate with data recorded by gauges located on the reference wetland site. Based on the monitoring results of Years 1 and 2 and considering the persistent drought conditions, it is concluded that the site is performing as designed. Weather station data from the Smithfield Weather Station were used in conjunction with a manual rain gauge located on the site to document precipitation amounts. The manual gauge is used to validate observations made at the automated station. On-site rainfall measurements were well below normal limits for the growing season due to the severe drought that NC experienced in 2007 (see Section 3.3.3). This Annual Report documents vegetation survivability based on twenty-two vegetationmonitoring plots, randomly located to represent the different zones within the project. The vegetation monitoring for 2007 documented a survivability range of 520 stems per acre to 800 stems per acre, with an average tree density of 651 stems per acre. Overall, the site is on track for meeting the initial vegetation success criteria of 320 stems per acre surviving after the third growing season as specified in the Restoration Plan for the site. During 2007 the restored stream channel remained stable and continued to provide the intended habitat and hydrologic functions. One bankfull event was recorded during the year. All monitored cross sections show very little adjustment in stream dimension, and it was concluded that the site remains on track to achieve the stream success criteria as specified in the Restoration Plan for the site.

INTRODUCTION

2.1

Project

The Cox wetland and stream restoration site is located near the community of Bentonville in Johnston County, North Carolina (Figure 1 and Figure 2). The site has a past history of 1

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) agricultural use consisting primarily of row crop agriculture. Ditches on the site were used to increase subsurface drainage when the land was under agricultural production. Construction of the site, including planting of trees, was completed in December 2005. Groundwater, surface water, and rain gauges were functional beginning January 2006. The 2007 monitoring season represents the second year of monitoring for the site. 2.2

Project Purpose

Monitoring of the Cox site is required to demonstrate successful restoration based on the criteria found in the Restoration Plan, and through a comparison to reference site conditions. hydrology, vegetation, and stream monitoring are conducted on an annual basis. Success criteria must be met for five consecutive years. This Annual Report details the results of the monitoring efforts for 2007 (Year 2) at the Cox Mitigation Site. 2.3

HYDROLOGY

3.1

Vegetation Success Criteria

As stated in the approved Mitigation Plan, to meet the hydrologic success criteria the monitoring data must show that for each normal year of rainfall within the monitoring period, the site has been inundated or saturated within 12 inches of the soil surface for a minimum of seven percent of the growing season (17 days). The day counts are based on the growing season for Johnston County, which is 232 days long (17 March – 5 November). As specified in the approved Restoration Plan, data are collected from five automated and five manual groundwater gauges. In addition, two automated gauges were installed in spring 2007 to augment the hydrology data. The Restoration Plan further specified that in order for the hydrologic data to be considered successful it must be demonstrated that precipitation is either within or below normal limits. 3.2

Description of Hydrologic Monitoring efforts

Five manual groundwater gauges, seven automated Infinities groundwater gauges, and one manual stream crest gauge were in-place throughout the 2007 growing season (Figures 3a and 3b). The monitoring protocol for the site specifies that automated monitoring stations will be downloaded and checked for malfunctions on a monthly basis. During monthly site visits, manual groundwater gauges are read, the crest gauge is read, and rainfall totals are collected from the onsite rain gauge. Automated Gauges

2

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) Automatic groundwater gauges record water table elevations twice daily at 08:00 and 20:00. Infinities gauges employ pressure sensors that record water elevation above the bottom of the sensor (with atmospheric pressure compensation). Immediately adjacent to each automatic gauge is a manual calibration gauge. The calibration water table depth is recorded at monthly downloads. To determine wetland hydroperiods, the automatically recorded data are compared to the calibration data to determine a standard correction factor between the calibration gauge and the automatic gauge for each location. The standard correction factor is applied to correct daily readings. The corrected daily readings are then used to determine wetland hydroperiods. Manual Gauges Water table depths are recorded monthly in manual groundwater gauges. To calculate wetland hydroperiods, interpolations are made between monthly readings by correlating twice daily automatic gauge readings. Each manual gauge is correlated to an automatic gauge based on proximity, landscape position, and the relationship of their groundwater depth readings (i.e. if their readings are separated by a consistent value). Once the appropriate automatic gauge has been selected a correction factor is calculated for each monthly gauge reading. This correction factor typically varies by several inches on a monthly basis. A daily rate of change between monthly correction factors is calculated to determine the daily correction factor. The daily correction factor is then applied to the automatic gauge readings to calculate an estimated daily water table depth for the manual gauge. These daily readings are used to determine wetland hydroperiods. Data Interpretation Wetland hydroperiods are calculated from twice daily water table depth elevations. A hydroperiod is calculated if the water table is equal to or less than -12 inches below ground surface for at least 24 hours. If a gauge falls below -12 inches for two consecutive readings (24 hours), then the hydroperiod ends at the last reading within -12 inches. If a gauge falls below -12 inches for only one reading then maintains a reading above -12 inches for a minimum of 24 hours, the hydroperiod is calculated continuously. This methodology accounts for minor technical malfunctions experienced by the automatic gauges. 3.3

Results of Hydrology Monitoring

3.3.1

Site Data

The following hydroperiod statistics were calculated for each monitoring station during the growing season: 1) most consecutive days that the water table was within twelve inches of the soil surface; 2) cumulative number of days that the water table was within twelve inches of the soil surface; and 3) number of times that the water table rose to within twelve inches of the soil surface. The results of these calculations are presented in Table 2. Figures 4a, 4b, and 4c provide charts of the water depth for each of the monitoring gauges on the site. Precipitation is shown in Figure 7. Raw hydrograph data collected from the monitoring gauges are provided in Appendix C. Year Two monitoring demonstrates that the site is functioning as designed, with varying degrees of wetness and saturation across the site. Gauges AW1, MW2, AW3, AW7, MW8, and MW9 exceeded the 7 percent hydrologic success criteria. Gauges AW5, MW6, and AW11 had significant hydroperiods of 4 to 5 percent of the growing season and outperformed some of the reference gauges but fell short of the success criteria. Overall, the mitigation site recorded a range of hydroperiods very similar to the range of hydroperiods recorded at the reference wetland site. As discussed in Section 3.3.3 below, 2007 rainfall was below normal limits for much of the growing season. 3

Reference Data

The approved Restoration Plan for the site provides that if the rainfall data for any given year during the monitoring period is not normal, the reference wetland data can be used to determine if there is a positive correlation between the performance of the restoration site and the natural hydrology of the reference site. The same hydroperiod statistics were calculated for each reference monitoring station during the growing season as were calculated for the site monitoring stations. The results of these calculations are presented in Table 3 and Figure 5. The reference gauges exhibit a range of hydroperiods similar to the mitigation site data, including two gauge locations (Ref AW1 and MW5) with a minimal wetland hydroperiod. The reference gauges are located in a riverine wetland upstream of the adjacent Westbrook mitigation site. Table 3.

Climate Data

The entire state of North Carolina experienced increasingly severe drought conditions throughout 2007, with some areas experiencing the lowest average stream flows on record. The first signs of drought began in February in the western part of the state. By early spring, abnormally dry conditions had spread across the state, and the western edge of the state began to see “moderate” drought conditions. From late spring through the summer, conditions steadily worsened. By August, 98 percent of North Carolina’s land area was designated as being in either “severe”, “extreme”, or “exceptional” drought. Additionally, lowest-ever average stream flows were recorded at 13 monitoring stations in August, including nine in central North Carolina, two in the mountains, and two on the coastal plain. Nearly the entire state was categorized as experiencing “extreme” drought in September, with the southwest portion of the state categorized as experiencing “exceptional” drought. Figure 6 depicts the increasing severity of the drought throughout the year. Drought Conditions Across North Carolina 1/2/2007 to 9/25/2007

Figure 6. NC 2007 Drought Conditions The Cox mitigation site experienced drought conditions consistent with state-wide trends. At the Smithfield monitoring station, near the Cox site, monthly precipitation levels fluctuated from the lower end of the normal range to over 1.4 inches below average from January through June (Figure 2 and Table 4). The Smithfield station received above-normal rainfall (6.45 inches) in July, but only 0.93 inches the following month; over 2 inches below normal. The Smithfield station received normal rainfall levels in September. The accumulated rainfall deficit, the difference between the long-term average and the observed monthly precipitation levels, aggregated monthly, grew steadily throughout the year to -17.44 inches in November. The high rainfalls in September were not sufficient to reverse the trend of an increasing rainfall deficit. Persistent and worsening drought conditions severely impacted the wetland hydroperiods and stream flow at the Cox mitigation and reference sites. 13

Hydrologic Conclusions

Data collected from all the groundwater monitoring gauges on Cox Mitigation Site indicate that six of twelve hydrology monitoring stations recorded hydroperiods of at least 7 percent of the growing season. Four of the remaining gauges recorded hydroperiods of 4 to 5 percent of the growing season. The remaining two gauges exhibited conditions similar to the range of conditions experienced in the reference wetland. Rainfall data demonstrated worsening drought conditions throughout the 2007 growing season. Based on the results from the mitigation site monitoring gauges during Years 1 and 2 and considering the results from the reference site gauges and the impact of abnormal drought conditions in 2007, it was concluded that the site is performing as designed. Particular attention will be paid to those gauges recording short hydroperiods in subsequent monitoring seasons.

VEGETATION

4.1

Vegetation Success Criteria

The interim measure of vegetative success for the Cox Wetland Mitigation Plan will be the survival of at least 320 3-year old planted trees per acre at the end of Year 3 of the monitoring period. The final vegetative success criteria will be the survival of 260 5-year old planted trees per acre at the end of Year 5 of the monitoring period. Up to 20 percent of the site species composition may be comprised of invaders. Remedial action may be required should these (i.e. loblolly pine, red maple, sweet gum, etc.) present a problem and exceed 20 percent composition. 4.2

The following monitoring protocol was designed to predict vegetative survivability: 22 plots were established on the Cox Wetland Mitigation Site, to monitor approximately 1.2 percent of the site. Fifteen of the plots are established next to the streambed to monitor the vegetation in the stream restoration buffer and riverine wetland zone. The other seven plots are randomly located to represent the non-riverine wetland zone on the site. The plots were randomly located within each zone and randomly oriented within the wetland restoration area. Plot construction involved using metal fence posts at each of the four corners to clearly and permanently establish the area that was to be sampled. Then ropes were hung connecting all four 15

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) corners to help in determining if trees close to the plot boundary were inside or outside of the plot. Trees right on the boundary and trees just outside of the boundary that appear to have greater than 50 percent of their canopy inside the boundary were counted inside the plot. A piece of white PVC pipe ten feet tall was placed over the metal post on one corner to facilitate visual location of site throughout the five-year monitoring period. All of the planted stems inside the plot were flagged with orange flagging and marked with a 3foot tall piece of half inch PVC to mark them as the planted stems (vs. any colonizers) and to help in locating them in the future. Each stem was then tagged with a permanent numbered aluminum tag. 4.3

Results of Vegetation Monitoring

Tables 6 and 7 present stem counts for each of the monitoring plots. Each planted tree species is identified across the top row, and each plot is identified down the left column. The numbers on the top row correlate to the ID column of Table 5. Trees are flagged in the field on an as-needed basis before the flags degrade. Flags are utilized, because they will not interfere with the growth of the tree. Volunteers are also flagged during this process. Table 6. Plot 1 2 3 4 5 6

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) Range of Stems/Acre: 520-800 Volunteer species will also be monitored throughout the five-year monitoring period. Below is a table of the most commonly found woody volunteer species. Table 7. Volunteers Tree Species ID Scientific Name Common Name A Liquidambar styraciflua Sweetgum B Red Maple Acer rubrum C Loblolly Pine Pinus taeda D Winged Sumac Rhus copallinum

FAC Status FAC+ FAC FAC No indicator

Volunteer woody species were observed in very high quantities in vegetation Plots 10 and 11, and if allowed to persist will exceed 20 percent of the total composition. Sweetgum (Liquidambar styraciflua) is the most common volunteer, though Red Maple (Acer rubrum), Loblolly Pine (Pinus taeda), and Winged Sumac (Rhus copallinum) were also observed. After construction of the mitigation site, a permanent ground cover seed mixture of Virginia wild rye (Elymus virginicus), switch grass (Panicum virgatum), and fox sedge (Carex vulpinoidea) was broadcast on the site at a rate of 10 pounds per acre. These species are present on the site. Hydrophytic herbaceous vegetation, including rush (Juncus effusus), spike-rush (Eleocharis obtusa), Boxseed (Ludwigia sp.), and sedge (Carex sp.), were observed across the site, particularly in areas of periodic inundation. The presence of these herbaceous wetland plants helps to confirm the presence of wetland hydrology on the site. There are quite a many weedy species occurring on the site, though none seem to be posing problems for the woody or herbaceous hydrophytic vegetation. The weedy species are mostly annuals and do not threaten survivability on site. Commonly seen weedy vegetation includes ragweed (Ambrosia artemisiifolia) and wild dill (Foeniculum vulgare). Any threatening weedy vegetation found in the future will be documented and discussed in future reports. 4.4

Vegetation Conclusions

The site was planted in coastal plain small stream swamp and wet hardwood forest species in January 2006. There were twenty-two vegetation-monitoring plots established throughout the planting areas. The data reflects that the overall site is on track to meet the interim success criteria of 320 trees per acre by the end of Year 3 and the final success criteria of 260 trees per acre by the end of Year 5 as specified in the Restoration Plan for the site.

STREAM MONITORING

5.1

Success Criteria

As stated in the approved Restoration Plan, the stream restoration success criteria for the site includes the following: Bankfull Events: Two bankfull flow events must be documented within the five-year monitoring period. Cross-sections: There should be little change in as-built cross sections. Cross sections shall be classified using the Rosgen stream classification method, and all monitored cross sections should fall within the quantitative parameters defined for "E" or "C" type channels. 17

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) Longitudinal Profiles: The longitudinal profiles should show that the bedform features are remaining stable, e.g. they are not aggrading or degrading. Bedforms observed should be consistent with those observed in "E" and "C" type channels. Photo Reference Stations: Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures.

5.2

Stream Morphology Monitoring Plan

To document the stated success criteria, the following monitoring program was instituted following construction completion on the Cox Site: Bankfull Events: A crest gauge was installed on the site to document bankfull events (Figure 3b). The gauge is checked monthly, and records the highest out-of-bank flow event that occurred during the past month. Cross sections: Two permanent cross sections were installed per 1,000 linear feet of stream restoration work, with one of the locations being a riffle cross-section and one location being a pool cross section. A total of 16 permanent cross sections were established across the mitigation site. Each cross section was marked on both banks with permanent pins to establish the exact transect used. Permanent cross section pins were surveyed and located relative to a common benchmark to facilitate easy comparison of year-to-year data. The annual cross section surveys include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg. Riffle cross-sections are classified using the Rosgen stream classification system. Permanent cross sections for 2007 (Year 2) were surveyed in August 2007. Longitudinal Profiles: A longitudinal profile of approximately 3,000 feet was surveyed along the restoration reach in Year 1. The longitudinal survey will take place in Years 3 and 5 as well. Measurements include thalweg, water surface, bankfull, and top of low bank. Each of these measurements is taken at the head of each feature, e.g. riffle, run, pool, glide, and the max pool depth. A common benchmark will be used each year to facilitate comparison of year-to-year data. No longitudinal profile was surveyed during 2007 (Year 2). Photo Reference Stations: Photographs are used to visually document restoration success. Reference stations are marked with wooden stakes and Global Positioning Satellite (GPS) coordinates have been determined for each location. Reference photos are taken at each permanent cross-section from both stream banks. The survey tape is centered in the photographs of the bank, and the water line is located in the lower edge of the frame with as much of the bank as possible included in each photo. In-stream structures (e.g., rock vanes, cross vanes, and constructed riffles) are also photographed. Photo reference stations will be photographed at least once per year for at least 5 years following construction. 5.3

Stream Morphology Monitoring Results

Photographs were taken throughout the monitoring season to document the evolution of the restored stream channel (Appendix D). Herbaceous vegetation is moderately dense along the restored stream. Pools have maintained a variety of depths and habitat qualities, depending on the location and type of scour features (logs, root wads, transplants, etc.). In-stream structures installed within the restored stream included constructed riffles, log vanes, log weirs, and root wads. Visual observations of structures throughout the past growing season 18

November 2007

Cox Mitigation Site Annual Monitoring Report for 2007 (Year 2) have indicated several areas requiring continued observation. The log weirs have experienced significant end cutting and undercutting that has resulted in head cuts migrating up the channel. Portions of the stream channel are showing bank erosion and sparse bank vegetation. Table 8 details the stream areas of concern. 5.3.1

Cross Sections

Year 2 cross section monitoring data for stream stability were collected during August 2007 and compared to baseline data collected in 2006 (Appendix B). All monitored cross sections fell within the quantitative parameters defined for "E" or "C" type channels.

Longitudinal Profile

A longitudinal profile survey was not conducted in Year 2. The previous profile and cross sections indicated there has been very little adjustment to the stream profile or dimension since construction. 5.3.3

Hydrology

A bankfull event 0.3 feet above bankfull stage was recorded during the February site visit. No additional bankfull events were recorded during 2007.

OVERALL CONCLUSIONS AND RECOMMENDATIONS •

Year 2 hydrologic monitoring has documented that suitable minimum wetland hydrology criterion was achieved across most of the site. Of the twelve hydrology monitoring gauges, six recorded consecutive hydroperiods for at least 7 percent of the growing season. The remaining gauges exhibited a range of hydroperiods similar to the range of hydroperiods recorded at the reference wetland. It was concluded that based on the monitoring results in Years 1 and 2 at both the mitigation and reference sites and given the abnormal drought conditions experienced in 2007, the site is performing as designed.

•

The restored stream channel has remained stable and is providing the intended habitat and hydrologic functions. All monitoring cross sections for 2007 showed little adjustment in stream dimension. Observation of stream structures will continue in 2008 and repairs will be undertaken as required. Overall, the site is on track to achieve the stream success criteria as specified in the Restoration Plan for the site.

•

Vegetation monitoring efforts have documented the range of surviving tree stems to be 520 to 800 stems per acre, with the average number of stems per acre on site to be 651, which is a survival rate of greater than 92 percent based on the initial planting count of 710 stems per acre. Based on the monitoring results of Years 1 and 2, the site is on track to achieve the interim vegetative success criteria specified in the Restoration Plan for the site.

•

All hydrologic, vegetative and stream monitoring will continue through 2010.
